[sane-devel] USB scanner module ioctl

[David Stevenson]

Another request for help

Has anyone used ioctl in the usb scanner module to read control data from a 
unit?

My first attempts to send control messages to the scanner returns no error.
But when I try to read data back I do not get the data I hoped for.
As the function returns immediately, has it had time to send the request to 
the unit and wait for a reply?
